IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 206,314, dated July 23,187'?- application filed June 1, 1878.

To all whom it may concern:

3e it known that I, JOHN GREIG-,of Morris, in the county of Grundy andState of Illinois, have invented a new and valuable Improvement inGates; and I do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a side View of myimproved gate. Fig. 2 is a top view of the same opened; and Fig. 3 is aside view of the open frame, showing the gate in section.

The nature of the invention consists in the construction and novelarrangement, in connection with a gate and its bars, of a post, having aswinging hanger provided with a central roller, and a horizontal guidebar seated in a groove in the hanger and extendin g on each sidethereof, and one of the bars of the gate bearing against said guide-barand the roller of the hanger, as will be hereinafter more fully shownand described.

I11 the annexed drawings, the letter A indicates a swinging and slidinggate, e011- structed with horizontal bars 12, secured at their ends andmiddle portion to vertical bars m. B represents the gate-post, havinghinged thereto the open box or frame 0, consisting of the vertical barsa and I), connected at their ends and provided with the roller (1, whichis pivoted between said bars at the proper height to form a bearing forthe rail a of the gate, which rests and moves thereon through the openbox or frame.

0 is the friction-preventing guide, which is a small horizontal barsecured to the inside of the bar a of the swinging frame, parallel withthe gate and above the roller sufficiently to bear against the side ofthe rail a, which rests on said roller. This horizontal bar 0 extends oneach side of the frame A in the form of arms, and is designed to preventundue binding and friction of the gate against the vertical bars of theswinging frame as the gaterail moves between them, which is accomplishedby the bearing of the projecting ends or arms of said bar against thebearing-rail a of the gate, which rests on the roller in the frame. Itserves also as a lever to assist in turning the hinged frame or fulcrumin the operation of swinging the gate around. In this operation thelateral bearing-surface of the gate is confined to that portion of thebar a which bears against the guide and friction preventer c, which,having a smooth and horizontally-extended surface always presented tosaid bar, keeps the roller opening square to the gate, and therebyeffects a free sliding motion, when otherwise the gate would bind in itsturning and sliding movements against the diagonally-opposite corners ofthe bars of the swinging box or frame.

This guide may be secured in a dovetail notch in the side of theframe-bar, or otherwise, as may be desired.

I am aware that a swinging or hinged frame for a sliding gate is notnew, and that a roller has been used to form the bearing for a slidinggate, and therefore I do not claim, broad- 1y, such devices; but

lVhat I claim as my invention, and desire to secure by Letters Patent,is

The combination, with a sliding and swinging gate, A, having bars a a,of the post I having the swinging hanger G, provided with a centralroller, (1, the horizontal guide-bar a, seated in a groove of the hangerand extending on each side thereof, the bar a, bearing against saidguide-bar c, and the roller d of the hanger, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
